An aerosol situation in the stratosphere over Tomsk is analyzed based on the data of lidar observations carried out from June 6, 1991 to March 6, 1992. It is shown that the first traces of the Pinatubo eruption were recorded over Western Siberia at the end of June about two weeks later the volcano eruption that is consistent with the velocity and trajectory of movement of the air masses at these altitudes during this period of time. Maximum loading of the stratosphere with aerosol of volcanic origin was observed on January 21 and 22, 1992. The scattering ratios determined during these days at a wavelength of 532 nm reached 9.5 at an altitude of 23.5 km. Such values of R were recorded over Tomsk for the first time during the last six years of regular lidar observations.
